TART II.] Anatomcial Distribution of the Ancsstkesia. 459 



38. Taking the regions of the entire body in order of number of cases, we find 

 the lower extremities occupying the first place, followed successively by the upper 

 extremities, the head and neck, and the trunk, the latter being only a little more 

 than half as frequently affected as the face. 



Proceeding to a more detailed account of the distribution of the anaesthesia, we 

 shall take up its several localities in the order of the table. 



1. The face. — In 20 cases the anaesthesia was complete over the entire 

 face. In those cases in which it was partial only, the precise distribution varied ; 

 in one case it was confined to the malar prominences, in another to the right malar 

 prominence and the centre of the forehead, while in a third there was complete 

 anaesthesia of one side of the face, the other remaining unaffected. The chin alone 

 escaped in 3 cases, along with the upper lip in another, and with the upper lip 

 and the angles of the lower jaw in a third. In 2 cases the forehead alone, in 1 

 the forehead and the upper lip, and in 1 the temporal regions alone escaped. In 

 4 cases the precise distribution was not determined. 



2. The ears. — In 18 cases these were entirely anaesthetic. In 1 there was 

 complete anaesthesia of the left ear only ; in 5 sensibility was impaired, although 

 not absent ; in 2 the tragi and interior surface of the ears escaped ; in 1 the 

 interior of both ears with the tragus of the right, and in another the interior 

 of the right ear alone escaped. 



3. The scalp. — In 8 cases anaesthesia was complete over the entire forehead. 

 In 1 it extended from the forehead halfway to the occiput ; in 1 it was present on 

 the left side only, and in 1 a certain amount of sensibility was retained throughout. 

 In 1 case the precise distribution was not determined. 



4. The neck. — Anaesthesia of the neck when present was in all cases complete 

 over the entire region, and its occurrence was always associated with very widely 

 diffused and extreme anaesthesia of the body generally. 



5. The ujoper extremities. — In 20 cases the entire upper extremities from the 

 shoulders downwards were completely anaesthetic. In 13 cases anaesthesia was com- 

 plete from the elbows, in 2 complete from the elbows save over the hollow in front 

 of the joint. In 1 case it was confined to the extensor surfaces from a little 

 above the elbows, and in another was complete from the elbows on the extensor 

 and only partial on the flexor surfaces. In 1 case the entire upper extremities, 

 save the ball and inner margin of the left thumb, were affected ; in one the entire 

 extensor surfaces with the flexor surfaces from a little above the elbows. In 1 

 case anaesthesia was not present save over the upper third of the inner surfaces of the 

 arms. In 1 case it was complete from the mid-forearms; in 1 it was complete 

 from the elbow downwards on the right side, but on the other was confined to the 

 hand; in 1 it was present from the elbow downwards on the right side for the 

 entire surface, on the left for the extensor surface only. In 1 case the left 

 extremity was entirely anaesthetic, whilst the upper portion of the right arm retained
